Abstract
The utility model discloses a kind of novel cable for engineering machinery, the some insulating barriers comprising sheath and be arranged in sheath and conductor, described conductor embeds and is fixed in insulating barrier, compact siro spinning technology between described insulating barrier, described insulating barrier and sheath compact siro spinning technology.The utility model solves the electric device etching problem that the reason because of wire causes, and improves electric device reliability, reduces maintenance cost.
Description
Technical field
The utility model relates to technical field of cable, particularly relates to a kind of novel cable for engineering machinery.
Background technology
The operational environment of engineering machinery is relatively more severe, and often contact with water droplet, steam, dust, greasy dirt, the cable be arranged in engineering machinery can be subject to the erosion of these materials unavoidably.In existing engineering machinery cable manufacturing technology, the insulating barrier cross section of insulated conductor is circular, therefore there is gap between insulating barrier, water droplet, steam, dust, greasy dirt can flow in the gap between wire insulation, corrosion wire and electric device, be therefore necessary to develop a kind of cable that can prevent water droplet, steam, dust, greasy dirt from flowing between insulating barrier gap.
Summary of the invention
For the problems referred to above, the utility model provides a kind of novel cable for engineering machinery.
The utility model is achieved by following technical solution:
For a novel cable for engineering machinery, comprise sheath and some insulating barriers of being arranged in sheath and conductor, described conductor embeds and is fixed in insulating barrier, compact siro spinning technology between described insulating barrier, described insulating barrier and sheath compact siro spinning technology.
The outside of described sheath cross section is circular.
The inside of described sheath cross section is square.
The cross section of described insulating barrier is square.
The beneficial effects of the utility model are:
The utility model is by adopting cross section to be that foursquare insulating barrier makes to closely cooperate between insulating barrier, thus water droplet, steam, dust, greasy dirt can not flow to electric device inside, solve the problem that the reason because of wire causes electric device to corrode, improve electric device reliability, reduce maintenance cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model cross-sectional structure schematic diagram.
In figure: 1-sheath, 2-insulating barrier, 3-conductor.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, for a novel cable for engineering machinery, comprise sheath 1 and some insulating barriers 2 of being arranged in sheath 1 and conductor 3, described conductor 3 embeds and is fixed in insulating barrier 2, compact siro spinning technology between described insulating barrier 2, described insulating barrier 2 and sheath 1 compact siro spinning technology.
Sheath 1 is the installation counterpart of wire, sheath 1 is made with polyvinyl chloride, there is certain elasticity, can according to suitable the bending of the needs of installation circuit, in existing wire laser diode attachment auxiliary, the mating surface of each wire laser diode attachment auxiliary is arcwall face, and in order to ensure that whole wire has good registration property installing and using in process, sheath 1 cross section outside is circular.Sheath 1 cross-sectional interior and insulating barrier 2 compact siro spinning technology, insulating barrier 2 cross section is square, and therefore sheath 1 cross-sectional interior is square.Sheath 1 adopts round outside but spuare inside structure, and adopts elastomeric material, not only can ensure inside and outside installation requirement, and has certain pressuring action to the insulating barrier 2 of inside, makes to coordinate between insulating barrier 2 tightr.
Insulating barrier 2 cross section in existing engineering machinery cable is circular, from geometry principle: between circle and circle the most closely fit system to be two circles tangent, will inevitably gap be produced when multiple circle is tangent, thus adopt arcwall face to coordinate and all can produce gap; Polygon and polygon the most closely fit system are that two polygonal a certain bar limits contact with each other, and can not produce gap after contact, thus adopt plane to coordinate and can not produce gap.Consider polygonal registration property, when quantity is more, regular polygon can realize closely cooperating arbitrarily, and non-regular polygon then can not realize closely cooperating arbitrarily, and the cross section that reach the object insulating barrier 2 eliminating gap must select regular polygon.Production practices prove, when the quantity on regular polygon limit is more, the error that the regular polygon processed produces is larger, the workload of comparison of dividing into groups in assembling process is larger, when such regular polygon quantity is more, error is by causing cooperation not reach requirement after accumulation, and the regular polygon therefore selecting the number on limit less in regular polygon is as the shape of cross section of insulating barrier 2.In regular polygon, equilateral triangle is the regular polygon of the minimum number on limit, but the number of equilateral triangle can not be combined into the outside assembly for regular polygon when being less than 6, and foursquare number can not be combined into the outside assembly for regular polygon when being less than 4, consider insulating barrier 2 assembly and the registration property of sheath 1 and the actual requirement of quantity in engineering machinery cable is produced of insulating barrier 2, select the square shape of cross section as insulating barrier 2.
In order to ensure the insulation effect of wire, conductor 3 embeds and is fixed on insulating barrier 2 cross-section center.Conductor 3 can produce heat in the course of the work, therefore insulating barrier 2 can generate heat, thus insulating barrier 2 has aging phenomenon, and aging speed and insulating barrier 2 are relative to the distance dependent of heat generating spot, distance hour electrothermal calefactive rate is very fast, slower apart from electrothermal calefactive rate time large, conductor 3 embeds and is arranged on insulating barrier 2 cross-section center, the volume being distributed in the insulating barrier 2 of conductor 3 surrounding is symmetry equivalent, degree of aging is impartial everywhere to make insulating barrier 2, be not easy the phenomenon causing insulating barrier 2 local ageing excessive velocities, guarantee the stable conditions of insulating barrier 2.Whole wire usually can be subject to outside irregular active force in use; the direction of these active forces cannot determined in advance; therefore all likely External Force Acting is subject at any direction of conductor 3 cross section; in order to avoid there is stress concentration point on conductor 3; the cross section of conductor 3 is done circular, while reducing conductor 3 self wearing and tearing, reduces the destruction of conductor 3 pairs of insulating barriers 2.
When using the technical program, the bearing power designed by wire and the material selected calculate the cross-sectional area of conductor 3; According to the cross-sectional area of the material determination insulating barrier 2 of the cross-sectional area of conductor 3, the maximum heating power of conductor 3 and insulating barrier 2; The cross-sectional area of sheath 1 calculates according to the cross-sectional area of insulating barrier 2 and quantity; The quantity of insulating barrier 2 is selected according to actual needs, if electrical appliance is single-phase electricity electrical appliance, then the quantity of insulating barrier 2 is 2, if electrical appliance is servomotor, transducer, throttle driver plate in engineering machinery, makes a video recording first-class, then the quantity of insulating barrier 2 is 4.
